This paper focuses on sustantial differences in the use of headdresses among prehispanic population in the valley of Azapa and coast of Arica observed during the Late Intermediate Period (1000 - 1470 AD) excavated at the Playa Miller-3 cemetery, in the coast, 233 graves with their funerary contexts contain 32 feather diadems. The analysis both of the context and the geographical distribution of such diadems allows us to associate this type of headdress with a specific group of fishermen. The revision of the archaeological material from the other coastal and valley sites in the Archaeological Museum of San Miguel de Azapa, has demonstrated, that such headdress survived until the beginning of the Late Period showing, therefore, a particular cultural continuity
